The two sat together and took in a match of the wheelchair tennis between Australia and New Zealand at the small venue. Both wore sunglasses on an uncommonly hot sunny day for Toronto in late September.

Markle, 36, recently told Vanity Fair they’re in love. Harry, 33, has been dating Markle since last year. He confirmed the relationship in November when he complained about intrusive press coverage.

The Vanity Fair interview prompted British bet-maker Betfair to offer 6-to-4 odds that the couple will be engaged by the end of 2017 and 3-to-1 odds that they marry in 2018.

Best known as paralegal Rachel Zane in the US legal drama, Suits, Markle has appeared on General Hospital, CSI: Miami, Without A Trace and Castle. She also is a campaigner for gender equality.
